Lexar Mobile Manager 4+

This app will transfer files to and from the Lexar flash drives, but only from or to photos, videos, music, voice recordings, contacts, and DropBox under iOS 12. It does NOT integrate with Apple’s “Files” app, so it CANNOT to transfer data to/from other, non-Apple software. Since most of the non-Apple software already integrates with Files and/or DropBox, there is hardly any need for this app. Before Apple introduced their Files facility there might have been some reason to put up with the limitations of this app. However, until Lexar decides to support Files, I recommend NOT purchasing Lexar’s Lightning-interfaced flash drives, because the only way to use them from iOS seems to be via this, inadequate, app.

I use this app and device to transfer photos and homemade videos from my devices onto my microSD card. I was able to send photos from my microSD card to others via iMessage! He liked mine so much He wanted one, so I bought him a lexar, as well. Great app, useful device.

UPDATE: some of you might try downloading the "lexar mobile manager user guide" from the Lexar website. It'll tell you what you can and cannot do with the Lexar device. Also, on the last page it will tell you which file types it is compatible with. Knowing the picture/video file types that IOS 11 uses (HEVC, HEIF) are currently incompatible with almost everything, I will not be upgrading to iOS 11 at this time.

Rarely recognized by iPhone8. Eventually if I plug & unplug over & over it MIGHT work, but could take 50 tries. Works fine on laptop windows 10. Drive worked perfect on iPhone for first week. I have been EXTRA careful with it. Randomly stopped working. Randomly works. The mobile app is decent, but it’s annoying to transfer files from phone memory to drive memory the way the app works. I will return it ASAP for a better drive. As a salesman on the go in great need of this, it has completely failed me more than once. Never rely on this to work!!! Negatives: No protection for either tip. No keychain. Unnecessary wire length between ends. All around terrible design by people who obviously never have had a need of something like this. Not user friendly. Won’t work when you need it. Expensive. Poor support from maker who point fingers. Positives: none. Do not buy this one.
